Résumé
Objective To study the treatment efficacy and safety of transjugular filter implantation combined with dorsal venous pressure thrombolysis in the treatment of lower extremity deep venous thrombosis.Methods According to the random digital methods,80 patients with lower extremity venous thrombosis were divided into 2 groups,40 cases in each group.The observation group was given jugular vein filter implantation combined with dorsal venous pressured thrombolysis guided by the radiologic intervention,and control group was individually given the dorsal vein of foot pressure thrombolytic therapy.After treatment,the clinical effect was compared between the two group.Results The application of urokinase aggregates and thrombolysis time in the observation group were significantly lower than those in control group,thigh and calf circumferences reduced length before and after thrombolytic therapy in the observation group increased significantly than those in the control group(t =1.35,5.42,1.83,0.89,all P ＜ 0.05).The total effective rate of the control group was 60％,which was significantly lower than that of the observation group 85％ (x2 =3.85,P ＜0.05).The incidence rate of complication in the control group was 32.50％,that in the observation group was 30％,there was no statistically significant difference between the two groups(x2 =0.67,P ＞ 0.05).Conclusion Transjugular filter implantation combined with dorsal venous pressure thrombolysis in the treatment of lower extremity venous thrombosis has better efficacy and safety.
